To a solution of imidazole (338 mg, 4.98 mmol) and triphenylphosphine (1.3 g, 4.98 mmol) in methylene chloride (10 mL) is added iodine (1.26 g, 4.98 mmol) in portions. The mixture is stirred at RT for 45 min then a solution of (2-methoxymethylphenyl)-methanol (630 mg, 4.14 mmol) in methylene chloride (3 mL) is added dropwise and stirring is continued for 3 h. The mixture is concentrated and the insoluble material is filtered. The filtrate is evaporated and the residue is purified by column chromatography using a gradient of 0-50% EtOAc/hexane as eluent to give the title compound.
